says Celts best options to replace Shaq are: 1) Bismack Byombo Congolese baller blocks, rebounds, and boasts a wingspan (7'7"); height (6'9"). Some question age: estimates range 18 to 22. Others question how high he will be drafted. Mock drafts project mid-lottery to late first round. 2) Lucas "Bebe" Nogueira: young Brazilian shot-blocking natural, runs like a gazelle, and can finish with a variety of dunks. Stands seven foot tall with a 7'6" wingspan; questions remain about his ability develop NBA body, considered light. 3) Jordan Williams, U Maryland: Listed as a power forward; 260 pounds gives the size and strength of a center; a banger; not blessed with speed or shooting skills, but crashes boards. 4) Nikola Vucevic: U Southern Cal, big man with ability to shoot; not athletic like Benson but range extends to the three-point line (34.9% from three). Keeps opposing defenders honest. Defensive skills mediocre at best. Could play a role similar to that of Rasheed Wallace. 5) Keith Bensen, Maryland, has needed athleticism, capable of running the open court and finishing alley-oops; uses 7'2" wingspan to shoot over defenders; 'pick and pop' player; more athletic Jermaine O'Neal; with Rondo's ability to drive and kick, Benson makes good offensive fit. Draft Express has Celtics taking Georgia Small Forward  Travis Leslie average 14.4 pts per game with FG% of 49.4%. NBA has C's picking Jordan Williams.
